The Wycombe boss hopes the impending replay at Villa Park graces the television screens - admitting the cash bonanza would ease the club's debt.
Left-back Joe Jacobson's nerveless penalty denied Remi Garde his first win as Villa boss at the 10th attempt, captain Micah Richards on target for the visitors.
"You're talking Â£144,000 for a TV game, so I'm hoping that comes in," said Ainsworth.
"And then I'm hoping the Villa fans will respect Wycombe again and turn up in numbers, not boycott Villa or anything like that, because we need the cash!
"I'm hoping the TV will be there again, there's a chance of that.
"The gate's going to be bigger than it was here, so we'll do a forecast on what it may mean to the club.
"But with my football hat on I know what it means in the hearts of my players, and there's not many players that get to experience something like this in their careers, so that means just as much as any amount of money.
"There's a couple of things that this draw will do.
"I look at the finances of this club, I'm well clued-up on that as everyone knows.
"I'm involved in everything, right to the selling of the kiosks at the club shop.
"I know the finances to the penny, so I know what this means for us and how much this will go to paying our debt off.
"But I know what it's going to mean to some of my players too, boys who weren't told they were good enough at times, free transfers and this group of never-say-die Wycombe Wanderers players."
Villa's disgruntled fans accosted captain Richards, protesting against the club's poor form, but then applauded Wycombe off the field.
Ainsworth made a point of thanking the travelling supporters for respecting his side's gritty performance.
"It's great and just fantastic for the Villa fans to clap us off, because they are in a bit of disarray at the moment," said Ainsworth.
"So for them to have the respect to do that for my boys, I'd just say thank you.
"We'll see what happens up at Villa Park, we'll be giving our all again.
"With a little bit of luck you never know what happens in this competition."
Embattled Villa boss Garde accepted the club must simply accept the protestations of supporters, and keep beavering away to turn their poor campaign on its head.
"We have to accept that, as a player, a manager, everybody at the club has to accept that criticism, because we are not winning - that's football," said Garde.
"The situation with Aston Villa is very difficult and makes some silly things happen sometimes.
"Everybody has to keep calm, face their responsibilities, look in the mirror and ask themselves what they can do to get out of this difficult situation."
